Yet this small spring carries the residue of a once-active devotional life, and its older name points toward a specific, named individual rather than the anonymous sacred landscape that holy wells often evoke.

When the Ordnance Survey mapped the area in 1840, the site was recorded as "Toberregan", the first element being the Irish word tobar, meaning well, combined with a personal name. Locally, however, it has long been known simply as "Egan's Well". The folklorist Caoimhín Ó Danachair, writing in 1955, documented the site as part of his survey of holy wells in County Limerick. Holy wells in Ireland were traditionally associated with particular cures and ritual practices; the faithful would perform "rounds", a prescribed circuit of the well, often on a patron saint's feast day, pausing for prayer at set points along the route. At this particular well, the rounds are no longer made, but Ó Danachair recorded that the water was formerly believed to cure headaches, a relatively specific therapeutic claim that suggests it once drew people with a genuine and pressing purpose.

The well sits on a riverbank, which means the ground around it is likely uneven and subject to ongoing erosion; the very process that has shaped the spring's current appearance has also slowly worn away whatever physical markers may once have defined it. There is no formal structure here, no carved stone or votive niche to orient a visitor. Anyone attempting to locate it should approach with patience and a copy of the 1840 Ordnance Survey map as a guide, bearing in mind that the feature Ó Danachair described as a slight trickle may have shifted or diminished further in the decades since his fieldwork. The site rewards careful attention rather than a casual glance.
